RAC集群安装错误集合

1.VIP验证报错

[INS-40912] Virtual host name:dena3vip is assigned to annother system

该错误是由于hosts里面配置的VIP ip被占用导致，更换掉IP即可

2.启动数据库提示 ORA-01092: ORACLE instance terminated. Disconnection forced ORA-30013: undo tablespace 'UNDOTBS1' is currently in use

SQL> startup;

ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-30013: undo tablespace 'UNDOTBS1' is currently in use
Process ID: 18539
Session ID: 16 Serial number: 5

改错误是由于实例所对应的undo_tablespace不一致，导致undo_tablespace出现争用。备份好spfile，修改对应undo_tablespace即可

该问题在创建数据库的时候提示过，但只是警告，被我忽略了。我怀疑是环境变量的ORACLE_SID与Policy-Managed创建出来的SID不一致导致的（未做测试，只是猜测）
